Welding is a fabrication process utilized to join metals or thermoplastics. It uses high heat to melt the parts together, causing fusion. Welding can be applied in many fields, including the field of medical devices manufacturing.
The importance of precision welding for medical equipment
Welding is used in manufacturing of medical equipment, rehabilitation apparatus, as well as wheelchair parts and accessories. It also plays an important role in the reparation of medical appliances. Welding establishes strong, resilient, and permanent joint links. It offers durability, structural integrity, biocompatibility, and the integration of the electronics.
Durability
With the use of welding it is possible to create medical devices that can withstand constant use, rigorous sterilization, as well as the stress typical for the human body. Welded components are durable and resilient, which substantially lowers the risk of device failure and ensures their longevity.
Structural integrity
Precision welding allows for the seamless joining of components made from various materials. It enables structural integrity of the medical device.
Biocompatibility
Welding is a production technique that ensures all the joints are uncontaminated and biocompatible. It prevents unwanted reactions from the patients’ immunological system.
Integration of the electronics
The use of precision welding in the medical devices manufacturing process allows for an effective integration of the electronics. It ensures the security of all the electrical connections and enables accurate data collection, as well as all-around device functionality.
How does precision welding affect the patients’ safety?
Precision welding ensures the functionality, reliability, and safety of the medical devices. It prevents microscopic inaccuracies which can have severe consequences. Precision welding can also help make sure that the medical devices meet the requirements of the health industry. In consequence, this method of production affects the patients’ safety and benefits them greatly, by warranting the security of welded parts.
Welding services for medical field
Two methods of welding are used in the medical field: laser beam welding and resistance welding. Both of them are compatible with most metals used in medical devices and can make small spot welds. Laser beam welding and resistance welding are also both suitable in a typical lab or cleanroom environment.
Laser beam welding
Laser beam welding, LBW in short, is a non-contact process that uses a focused beam of light to melt two pieces together. This method is characterized by high-power density and small heat-affected zone. It is easy to automate and does not require a vacuum chamber. Laser beam welding creates robust, hermetic seam welds and is used in the production of hypotubes, pacemakers, stents, drug pumps, and implantable valves.
Resistance welding
Resistance welding, RW in short, uses current resistance to generate welding heat. It can create a fusion, solid-state or reflow weld. With the use of this method it is possible to produce an internal weld that is not exposed to air. It means the use of a shielding gas that prevents contamination is not necessary. Resistance welding is a perfect technique for joining thin foils and fine wires. It is especially useful when one or both components are plated with gold, tin or solder. Resistance welding is commonly used in the production of pacemakers.
